Hi Mario, No, you're not missing anything: one of the limitations of raytracing is that it does not handle solid volume displays. Raytracing limitations are listed at the bottom of this page: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/raytracing.html> Perhaps there are some Volume Viewer settings or data filtering that can improve the appearance in Chimera. In Volume Viewer, use the Features menu to show "solid rendering options". There is also a Volume Filter tool with various smoothing capabilities. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/volumeviewer.html#dispsolid> <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/volumeviewer/gaussian.html> I hope this helps, Elaine ---------- Elaine C.

Hi, I am trying to render an image that includes a difference map density displayed as a solid object. When I try to get the image directly from the screen it shows patterns of pixelation. I then tried POVRAY and the solid object data does not show up. Is there anything that I am missing? Thanks
